Mender is an end-to-end open source software updater for embedded Linux devices.
Mender is a server-client application that allows you to deploy an image-based update from the server-side component to your connected clients (device or fleet of devices). The deployment is done securely using HTTPS and the partitioned setup (dual A/B rootfs partition) makes sure your device will stay up and running should anything interrupt the update process.
Hosted Mender delivers a secure and robust update server as a service and now it is fully integrated in the Toradex Easy Installer image format. This integration enables Over The Air (OTA) updates in a out-of-the-box experience for Toradex customers.
The following Computer on Modules are supported:
While you can use a wide variety of displays and monitors, additional configuration may be required for a specific setup.
A section in the end of this guide provide instructions about display and touch screen configuration.
